Mai dreams about the school and notes that dozens of spirits, including will-o'-the-wisp, are devouring each other. Masako and Mai later see Saukichi's ghost being similarly absorbed. The team discover a popular spirit-summoning game, 'Orikiri-sama' may have been spread by Saukichi, possibly resulting in the many spirits inhabiting the school. While retrieving a video tape, Mai finds herself locked in a room with bottles crashing down around her, releasing the smell of formalin.
